few weeks behind everyone else... my 2.80 P4

[JCviggen]

here's default voltage for ya ;)

It looks pretty good, and it runs 3D at that speed and voltage too. Only problem is that my P4T533 seems a bit quirkt with C1 CPU's ... already noticed it when I had OPP's ex 2.66 in my rig ... it wouldnt run 3D at nearly the same speed as him but it would boot as high as he could.. weird. i'll try an IT7 one of these days.

The max I can run 3D seems to be around 3640 on this board. 1.70V. Any higher than that just makes things worse.

I've been doing some 3D now at 169x4 RDRAM. My Radeon only clocked a lowly and stock 370/340. I still managed to equal/pass OPP's framerates in the lobby test with the memory clocked this high. With a Radeon at 450+, this would fly ...





a few more screenshots


so its not a bad chip, but I might have to look at buying another mainboard :( Although I think I would have to surpass my CPU speed by a pretty big margin to compensate for the awesome memory performance I have now...

Anyway, we're not done yet ;)

Very nice JC...give her hell :)

Nice nice man.....now I need one :D

dude.... i'm scared!
Good job... hope to see u stable at 4GHz!

[chainbolt]

CViggen, this is awesome!

What is a little surpising though is your "low" 3Dmark 2001 value (of course not really low :)). You have here a highly overclocked system AND you have RDRAM. With both you should come close to 19,000.

I have my 2.66 running at 3300 Mhz and with a non modified Radeon 9700 on an IT7 get almost 18,200 points. I know that my P4T533 always gave me 200 to 300 points more than a comparable DDR machine and the much MHz you have here. Or didn't you overclock the Raedeon 9700 :D

[JCviggen]

the IT7 board has helped my cause... I can now do 3D over 3.7 GHz :)

also got a slightly higher screenie

http://service.madonion.com/compare?2k1=4559526 radeon ar default and only 133 MHz on the memory (4:3) since this DDR400 from Kingmax seems to suck ass... happy its not my stick

[chainbolt]

This is my 2.66 on a Vapochill. Not bad, isn't it? It goes definityly better on the IT7-II than on the IT7, I think Abit has changed/improved components. Maximum in 3:4 is 176 Mhz, then the RAM is at almost 240 MHz.

[JCviggen]

as I told you on the [H] , you always seem to get the lucky stuff ;) very nice :)

how do you think about the 4T4A situation? It was my great hope, and now it looks bad, I fear. I don't expect much from the MSI 850E MAX

[JCviggen]

I dunno m8 .... MSI and overclocking ? Not sure... i've never really known any MSI board to be used to make great scores. The EPoX 32-bit RIMM board seems to be a new low in EPoX boards... and i thought the 8K7A was hard to beat.

My ASUS works fine in principle , 168x4 RDRAM in 3Dmark , but for some reason it goes like crap with C1's. It will load windows very high, but I cant do any 3D or CPU intensive stuff past 3.6 GHz. On this ABIT, 3.7G goes smooth...

I see it same:

- big shame for Epox (I never liked them, had to RMA 4 boards in a row)
- MSI - no good for overclocking
- IT7 better for overlocking, but poor DDR bandwidth.

Hopefully Asus is coming with a revision 2 of the P4T533

[JCviggen]

I think when you run in the 230's with DDR, its not that far behind RDRAM anymore. Sure you'll never catch up with it, but it gets close enough. With the extra CPU speed you can get the combo should be faster...

[Chong345]

Very nice JC :D :toast:

Have you gotten another Radeon to complement you chip?

Chong

[PiLsY]

Eyes open for a soltek 850E board sometime before christmas. No better date than that but it looks like a stormer. Apparently no voltage issues at all.

The MSI and Asus boards share the same voltage problem - dont touch either. The Epox board I wouldnt buy on principle (9 times burned 10th shy).

Anyway, im happy with the IT7 as is. I certainly didnt notice any better ocing on the IT7-2. Infact the opposite - my IT7-2 was crap and got RMAd for another IT7. None of that ECS rubbish for me thanks.

JC - Try and find somewhere in Europe that sells Via boards m8 (as in Via branded and manufactured). Theres a storming P4X400 board out there. Ive seen some cracking memory scores and some very good o/c results from it. I just need to find somewhere to get one :p. Failing that the Soltek SL85-ERV looks VERY good. Silver PCB, P4X400, agp, cpu and dimm voltage adjustment. FSB up to 250mhz in 1mhz increments. The list goes on. A very solid looking performer. The via chipsets aside I think the only way to go if youre not using an IT7 would be either the Asus P4B533-E or the Albatron 845E Pro S(ilver). Im trying to decide whether to switch mobos. Getting bored with the IT7 :p.

In fact, the VIA (VPSD) P4PB400-FL is sold in Germany.

The Soltek really looks very promising. Does it have an AGP-PCI-Lock? Sad thing is that i only found a store in the UK that sells it. :(

[JCviggen]

Well I tested the following memory on the IT7 max2 (memory by Entuscan)

- Twinmos PC3200 Samsung 4ns and Winbond 5ns.
- Corsair PC3200 C2
- Mushkin PC3200 & HP 2700 C2 2-2-2

result : this board sucks ass, or 2.80Vddr really isnt enough.

The Twinmos refused to do 200 MHz. the one with the winbond chips got a bit higher but still failed. The winbond one had been confirmed to run 200 max timings in a KR7A though. No go on this board.

The Corsair went best of all. It would do about 220 on slowest possible timings. Both the mushkin sticks failed to do this, although the PC2700 HP stick had been confirmed as the best of the bunch on a KR7A. There was also the Kingmax PC3200 stick, which will top out at a whopping 155 MHz slowest timings on this board. I tried all the memslots too.

I'm really confused about what to do now :(

[PiLsY]

I tried the IT7-2 as well m8 and my board sucked. Its a proper POS. Just stick with the standard IT7 or go for an albatron. Those via boards do like very very smart though.

Thats the exact model board im looking for cobase. Which store sells it and do you know if theyd ship to the UK?

PiLsY.

[Jupiler]

JC :
the board really needs more memory voltage than the 2.8V standard.
I've got my corsair stick running 223Mhz, 2-7-2-3 at 2.9V. Even 200 Mhz 2-5-2-2 needed 2.8V to run stable. This on the IT7, of course, not the IT7 MAX 2.
A modded AV bios is needed for the IT7 Max2.

or some soldering...

What happened to that magic Samsung stick of yours? :)

[Jupiler]

Oh, still have it here and I'm not gonna sell it :)
Max I could get out of it was 242 Mhz on this board.
Still, I'm glad that the IT7 gives you a better oc than the P4T533. Same for me, the IT7 oc way better than the TH7 II did

That's the shop: http://www.ble-computer.com/

Never ordered from them though, found them through "Geizhals.at", much the same as "Pricewatch".

[PiLsY]

Ive got a bios here thatll get you the standard 3.2v dimm selection via softmenu. What voltage you actually get is down to the board and your PSU, but itll probably be between 2.95 and 3.25v.

FYI any IT7 bios from 8z upwards will work on the IT7-2 with no loss of functionality :).

If any of you want it mail me @ pilsy@teamshs.com

PiLsY,

You think the PSU has to do with the mobo unable to go higher with mem voltage, how???

Thanks,
OPP

[Chong345]

OPP,
I can't explain it but on mine it actually did. Remember for the Geil review I told you my mem voltage was stuck at 2.96v-2.94v. I adjusted my potentiometers on my PSU so that my 5 and 12 were always above 5 and 12 even at full load. Now I get 3.07v on the VDIMM:D. Don't ask me why this happened the way it did but I'm not complaining. Now if I could just get that extra 0.13V ;)

Chong

[libertate]

Hey Pilsy, does the P4B400 have a 3:4 mem ratio?
I see in the manual that you can set it to 266/333/or 400....

what I'm especially interested in is that it has dram command
rate, burst length, and queue depth....

I have a 2.66 that I'm predicting will do at least 3.6 ghz with
chilled water, that would be 480ddr with 3:4... but if it'll
only let me run 400 ddr no matter what the host fsb,
I wouldn't be interested....

Also, it only has 2.8vdimm, have you heard if it stays
close to this in actual volts? For example, 2.7-2.75 would
be fine to run my twinmos tcb3 6ns up to some high speeds...

I'm soooo interested in this board :D

Interesting, good thing I have new PSU coming soon, maybe this will help.

[Chong345]

I am using a PC Power and Cooling PSU 475ATX Turbo Cool that is modded so that the pots are external. Its great cause they have seperate pots for the 3.3v, 5v, and the 12v. :D

Chong

[OPPAINTER]

Whats the Model #?

OPP:)

It's the TurboCool 475 ATX. The beauty with these guys...is you can have whatever amps you want on the various lines thru special order, along with the externally adjustable voltage option. These PSU's are built like a brick and put out some incredible juice...the line conditioning which keeps the DC current consistent regardless of the AC dropping as low as 85v is in itself worth the price of admission. I've had mine since Nov. of last year(TurboCool 450 which is no longer produced) and its solid as a rock.

I'd recommend minimum of 50 amps on the +5 and 45 amps on the +3.3 if you custom order. My 450 came setup that way..but the stock 475 does not.

Randi:D

[Chong345]

Like MrIcee said this thing is like a rock. I get little to almost no fluctuations on any of my rails. The most I see is like .03V either way. Its sweet. Very nicely crafted and if you look in the inside you know why they are so expensive. I mean this thing is a monster.

Chong

[PiLsY]

Firstly - the via board.

It has 5:3 , 4:3 , 1:1 , 3:4 , 4:5 memory options.

These allow you to run...

100/100
100/133
100/166
133/100
133/133
133/166
166/100
166/133
166/166

Plus whatever custom settings you choose (ratios available at every FSB - the only limit is memory speed cant be lower than 100mhz so no 100/66 option).

Vcore from 1.1 to 1.85v
Vdimm from 2.5 to 2.8v
Vagp from 1.5 to 1.8v
FSB from 100 to 200mhz in 1mhz steps

Looks like a little stunner.....


Now the PSU thing. Adjusting the POTS made little or no difference to my vDDR. However, changing PSUs did. Even when the voltages were adjusted to be identical (or as near as damnit). I believe this is down to the actual signal strength/clarity supplied by the PSUs as opposed to anything else. However, you have nothing to lsoe by adjusting your PSU so give it a try. The major difference though comes from board to board. Differences in vDDR were less than 0.1v between PSUs I tested, with my usual Enhance 0246 rev 2.1 coming out on top (again :P). Until I can get hold of PC Power PSU i cant se ethis PSU leaving my system. Not even the 550watt antec truepower can match it.

PiLsY.

[libertate]

This is the same via board you're talking about right?
http://www.newegg.com/app/viewProduct.asp?description=13-181-005&depa=1

Does it have fixed 33/66 PCI?

So I could lock that in, run the FSB up to 185, do 3:4 mem?
Just like I could on an i845d/e ?

That would be awesome, it would make it possible tohave 98%
bandwidth efficiency even at high mem speeds like 460 and on up...

[PiLsY]

That board is the P4PB 400, the one I have seen results form is the P4PB 400-FL. As far as I am aware though the only difference is onboard Firewire and Lan.

It does NOT have pci/agp fix - thats an Intel feature. However, it does have the 1/5 divider, so at 185 FSB your PCI speed would be 37mhz and AGP 74mhz :).
